RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 782,157, dated February '7, 1905.

Application filed April 2, 1904. Serial No. 201,210.

Be it known that we, EDWIN (i. MICK and JAMEs M. GILLILAND, citizens of the United States, residing at Newcastle, in the countyof Lawrence and State4 ot' Pennsylvania, have made certain new and useful .Improvements in Railway-Switches, ot' which the following' is a specitication.

This invention is an improvement in railwa. v-switches; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed..

In the drawing's, Figure l is a top plan view, partl'vY in section, ot' a switch embodying' our invention, the main line being open. Fig. 2 is a similar view with the switch open. Fig'. 3 is a detail side view showing the pressurebar t'or restraining the automatic switch-operating' means from action when the weight ot' the train is on such pressure-bar. Fig'. L1 is a detail cross-section on about line 4 4C o't' Fig'. l. Fig. et" is a section somewhat similar to Fig'. 4, showing' the operation of the wheels in depressing the pressure-bar. Fig'. el" is a detail view illustrating the arrangement 0i bolts t'or connecting' the roller-point and the guard-rail. Fig'. 5 is a detail elevation, partly in section, on about line 5 ot' Fig. 2. Fig'. 6 is a detail cross-section on about line 6 6 ot' Fig'. 2. Fig'. T is a vertical sectional view, and Fig'. 8 is a horizontal section, showing the operating' device and its connections with the crank and vpitman for operating' the switch. Fig'. 9 is a sectional plan view showing' the construct-ion in the region ot' the point between the adjacent ends of the. uniting-sections of the main line and siding'. Fig'. l0 is a vertical section ot' the lamp-shaft and the lantern thereon and the tube for rotating' the lantern. Fig'. ll is adetail perspective view showing' the lantern and its tube detached, and Fig. l2 is a detail perspective view showing' the lamp and its shaft or standard detached.

1n carrying' out our invention we provide, together with the main line and the switch or siding', means for positively operating the switch in one direction, autoinatically-operating devices in the t'orm ot' springs, which operate the switch in the opposite direction, and a pressu re-bar which is connected with the switch and is arranged when moved to one position to be held by the weight exerted b v -wheels on said pressure-bar, so that the weight ot the train on the pressure-bar will restrain the action ot' theautomatically-operating' switch-operatingdeviees until the train has passed otiV such pressure-bar, when the automatic devices will readjust the switch. The purpose otl this construction, as will more Fully appear hereinafter, is to permit a brakeman or other operator on the train, by means of the operating' devices, to positivelyopen the switch to the position shown, for instance, in Fig'. L).

This operation tends to throw the pressurel bar from the position shown in Fig. 3 to that indicated in dotted lines in the same ligure, and in this position the weight ot' a car exerted b v one or more wheels 0n such pressurebar will hold the pressure-bar in such position and will keep the switch open until the last wheel ot' the train has passed oliA the pressurebar, when the spring devices will readjust the switch-point from the position shown in Fig'. Q to that shown in Fig` l, so that a brakeman after he has once set the switch and the lirst wheels ot' the locomotive have passed on the pressure-bar can get on the train after locking' his switch-lever and the switch will automatically readjust to open the main line.

In the construction shown the track includes the unbroken main rail A, the main-rail sections B and C in alinement with each other and opposite the rail A, the rail-section C being' `in the form of a switch-point at C, as shown in Figs. l and 2, the switch-point D movable at its point D' against and clear ot' the rail A, as shown in Figs. 2 and l, the switch-rail E, and the rail-sections B and E, jointed at and a at their ends adjacent to the rails B and E and coinciding at their meeting' ends at F, as shown in Figs. l and Q, so that the ends F ot' the rails B and E mayv be moved in and out between the positions shown in Figs. l and 2, the rails B and E beingtorced b v the wheels ot' a train when they pass onto the point D' from the position shown in Fig. l t0 that shown in Fig'. 2 and being' readj usted by the springs(best'shown in Fig'. il) from the understood from Fig. 1 of the drawings.

position shown in Fig. l to that shown in l Fig. 2 in the operation of the invention. In effecting the joints at CZ between the point D and its coinciding switch-rail and also at and e we may simply employ {ish-plate straps bolted tothe meeting ends of the rail and lying in the hollows of the rails, as will be At their meeting ends the sections B and E are rounded, one being made concave and the other convex to fit therein, and the joint is suiciently loose to permit the movement of the sections between the different positions shown in Figs. 1 and 2.

To press the sections B and E normallyin the position shown in Fig. 1, we provide springs G, operating in barrels G', secured on the outer sides of the sections B and E on opposite sides of the joint F and pressing against heads G2, operating in the outer ends of said barrels and connected together by a bar G3, from which rods G4 pass inwardly through the heads G2 and the'springs G., thence through the rail-sections B and E, and thence through the point of the rail C and through the frog H and are secured by nuts G5, as best shown in Fig. 9. This construction serves to normally hold the rail-sections B/ and E in the position shown in Fig. 1 and to readjust them to such position from the position shown in Fig. 2, and in order to aid the springs G we prefer to provide a supplemental spring g, operating in the barrel g upon a rod g2, projecting from the rail-section B, as shown in Figs. 1, 2, and 9 ofthe drawings.

A spring I, operating in an opening Il on the track against a head I2 on a rod I2, connected with the switch-point D, operates to press such switch-point normally from the position shown in Fig. 2 to that shown in Fig. 1, and thus aids in opening the main line and in holding such main line open except when it is positively closed b'y the operation of the switch-lever.

v,The switch-stand J has a shaft J provided with a handle-lever J2, which may be locked at J3, and is provided at its lower end with Ya pinion J 4, meshing with a pinion J 5, to which is connected a crank J6, connected with one end of a pitman K, whose other end operates in an opening K', formed in the bed of the track by means of suitable castings or beams, and such end of the pitman K operates against the outer end of a switch-bar K2, which is movable in an opening K3 and has a shoulder K4 pressed against a spring K5 to press the Switch-bar normally to the position shown in Fig. 1. rIhis switch-bar is broken into sections at K, with the sections connected by a turnbuckle K, as shown in Figs. 1 and 2, for purposes of adjustment, and the section K7 is connected with the switch-point D and eX- tends beyond the same at K8 and connects with one arm of a bell-crank lever L, whose other arm is connected by a pitman L, having for purposes of adjustment a turnbuckle L2, with one crank-arm, M', of a short shaft M, having another crank-arm, M2, which is connected with the pressure-bar N, the latter being supported on opposte sides of the crankshaft M by links M3 of equal length with the crank M2, so the pressure-bar M will be properly supported throughout its `length and may be rocked between the position shown in full lines and that indicated in dotted lines in Fig. 3 of the drawings. In the operation ofthe described construction it will be noticed that when the switch-point D is thrown from the position shown in Fig. 1 to that shown in- Fig. 2 the pressure-bar N will be moved by the action of the cranks M and' M2 from the position shown in full lines, Fig. 3, to that shown in dotted lines in the same ligure, in which the cranks and links N 2 and M3 will pass the center, so that if a wheel be run on the rail, as indicated in dotted lines, Fig. 3, it will prevent the pressure-bar from moving between the position indicated in dotted lines and 'that shown in full lines and will thus hold the switch-point D until the last wheel of a train has passed off the pressure-bar N, it being understood that this pressure-bar is made in practice of sufficient-length to extend between'any two wheels on the same side of a train, so that they cannot readjust between the wheels, but will be held down until the last wheel of the last car has passed over the pressure-bar. At such time the automaticallyoperating devices will act to readjust theswitch-point .D and the rail-section BVand E' from the position shown in Fig'. Q to that shown in Fig. l. In operation it will be understood that after the brakeman has manipulated the lever J2 to open the switch, as shown in Fig. 2, and the first wheel of a train has moved onto the pressure-bar the brake- IOO man can then throw the lever J2 back to the position shown in Fig. 1 and lock it in such position, as is usual, the break at 7c between the pitman K and the switch-bar K2 permitting the reverse movement of the pitman K Without moving the switch-point. Thus the switchman can set the switch devices to open the switch and can after the train has moved onto the pressure-bar get on the train and the train move on in safety, knowing that the switch will automatically readjust to open the main line by the action of the spring before described.

rI`he lamp O is mounted on the upright or shaft O/, which does not rotate, and the lamp is held from rotating by keying it upon the upper end of the rod O, as shown in Fig. 12. The lantern or lamp-casing' P, which may have glasses of different colors, is supported upon the sleeve P, which rotates about the upright O and has at its lower end a crank P2, connected by a pitman P3 with one end of a lever Q, which lever is pivoted at its other end Q and is connected between its ends at IIO Qi with the switch-bar, so that as the switchbar moves back and forth it will operate to give the lantern a quarter-turn to bring the red or green lig'ht into alinement with the track. lt will be noticed that the lamp docs not revolve, but that the lantern revolves about the lamp or light. rlhis is important, as if the lamp were revolved by the operation of the switch devices the sudden operation mig'ht operate to exting'uish the light, and this we avoid by making' the lantern or lamp-casing' to revolve about the fixed lamp or light. As shown, the lantern Pis separate from its sleeve P and has at its lower end a depending tubular portion p, fitting over the upper end of the sleeve P and having' at p a slot which receives a pin pi on the sleeve Pl, so the lantern will be positively operated with the movements of the sleeve P.

From the foreg'oing' description the construction and operation of the several parts will be understood. lt will be understood that as the train passes from the siding onto the main track the switch will open automatically by the pressure of the flanges of the wheels, permitting' the train to pass through the switch onto the main line. In this operation it will be'seen that as the train comes from the siding passing' onto the switch-rail thel flange of the wheel will force the rails into position to permit the train to pass onto the main track and also to operate the pressure-bar in moving thereon.
